The standard system (RPO IO5) features gesture control (use simple gestures such as tap, drag and swipe to navigate through menus and screens), in-vehicle apps via Shop, Apple CarPlay™ and Android Auto™ compatibility, and natural language voice recognition. The available system (RPO IO6) with embedded navigation offers easy-to-understand turn-by-turn directions. Navigation features can be accessed using the touch- screen, voice command or within the instrument cluster using the steering wheel-mounted buttons. Projected Buick Tri-Shield logo opened and closed by simply using a kicking motion under the driver’s side of the rear bumper, just left of center. It also features a Buick Tri-Shield logo that is projected onto the ground by an LED lamp under the rear bumper to indicate the hands-free sensor location. The key fob must be within 10 feet (3 m) of the back of the vehicle to activate the projected logo. The projected logo may not be visible in all conditions, such as on snow-covered ground or on a bright, sunny day.

The SmartSlide 2nd-row seat on the passenger side of the vehicle can be slid and angled forward using the handle on the side of the seatback, allowing passengers easy access to the 3rd-row seats on the curb side of the vehicle. The seat slides and tilts forward even when a forward-facing child restraint is installed using the LATCH system. Remove a rear-facing child restraint before moving the seat for 3rd-row entry or exit.
